Platt and his team initially left the baby swans, which are known as cygnets, with their parents for the first few days. When the birds started venturing into the lake on their own, city crews scooped them up and took them to a secure location to be cared for until they could safely care for themselves.

"Last year we had a lot of problems with theft of the eggs, and we just didn't really want that to happen this year," Platt said. "We really care about our swans."
